The men were reportedly killed during an attack in Amchide, an area near the Nigerian border, at about 8:30pm on Thursday night, according to a top security source.
The source disclosed that the militants attacked the defence and security forces in their hundreds, but met their Waterloo.
The incident came some months ago after at least 200 of the militants were killed by the army in Amchide and Limani, another part of northern Cameroon.
